Save This Mardi Gras shrimp sandwich features crispy fried shrimp marinated in buttermilk and hot sauce, coated with a seasoned flour and cornmeal mix, then fried to a golden crisp. Topped with fresh iceberg lettuce, ripe tomato slices, and thinly sliced red onion, all nestled inside a crusty baguette. A punchy remoulade sauce made with mayonnaise, Dijon mustard, horseradish, and spices adds a creamy, tangy kick to every bite. Perfectly balanced with Southern flavors, it’s an ideal handheld meal for festive gatherings or casual lunches.
The first time I had a proper shrimp po boy was in a tiny corner shop in the French Quarter, where the owner called everyone baby and the air smelled like fryer grease and heaven. I watched him assemble sandwich after sandwich with this hypnotic rhythm, shovel crispy shrimp onto bread with practiced hands. My shirt was covered in cornmeal dust by the time I left, and I didn't even care.
Last summer I made these for a backyard party and my brother stood over the stove eating shrimp straight from the paper towels, claiming quality control. By the time I actually assembled the sandwiches, half the shrimp had disappeared, and nobody even complained about the improvised portions.
Ingredients
- Large shrimp: Peeled and deveined saves so much time, and bigger shrimp means fewer to fry
- Buttermilk and hot sauce: This marinade tenderizes while building layers of heat
- Flour and cornmeal mixture: The cornmeal is non-negotiable for that authentic crunch
- Paprika, cayenne, and garlic powder: This trio creates that signature Cajun kick
- Mayonnaise: Use real mayo, not the healthy stuff, for the remoulade base
- Dijon mustard and horseradish: These give the sauce its signature bite
- Capers and parsley: Fresh touches that brighten all that rich fried goodness
- Crusty French rolls: The bread needs to stand up to those saucy, messy ingredients
Instructions
- Marinate the shrimp:
- Whisk buttermilk and hot sauce together in a bowl, add shrimp, and let them soak up that tangy heat for 15 minutes while you prep everything else.
- Make the coating:
- Combine flour, cornmeal, and all those spices in a shallow dish where you can really press the shrimp into the mixture later.
- Heat the oil:
- Get about two inches of oil hot in a heavy skillet until it reaches 350 degrees.
- Coat the shrimp:
- Shake off excess buttermilk from each shrimp and press them firmly into the flour mixture.
- Fry in batches:
- Cook shrimp for 2 to 3 minutes until golden and ridiculously crispy, then drain on paper towels.
- Whisk the remoulade:
- Stir together all sauce ingredients until smooth and taste it.
- Build the sandwiches:
- Slather remoulade on both sides of each roll, then pile on lettuce, tomato, onion, and lots of shrimp.
- Serve immediately:
- These wait for no one.
Save My friend from Baton Rouge told me that the true sign of a good po boy is when you have to lean over your plate to catch all the falling crumbs, and honestly, she is right.
Getting That Perfect Crunch
The cornmeal in the coating is what makes these shrimp unforgettable, so do not skip it or substitute more flour. I have tried both ways and the texture difference is night and day.
The Remoulade Secret
Let the sauce hang out in the fridge for at least 30 minutes before serving. All those flavors need time to become friends, and the sauce will taste twice as good.
Serving It Up Right
Wrap the bottom half of each sandwich in parchment paper to hold everything together when people take that first huge bite. It also makes the whole experience feel way more authentic.
- Have extra napkins ready because this will get messy
- Cold beer or crisp white wine cuts through all that richness perfectly
- Cajun fries on the side make this a complete meal
Save There is something deeply satisfying about food that requires multiple napkins and total commitment to eating. These shrimp po boys are exactly that kind of wonderful.
